Hi Madmike187777,
Thank you for reporting your experience of the issue. In case you haven’t seen it yet, I update my post on the issue: [Known Issue][PS4/XB1] Loss of interactions
The team believe they may have found the cause of the issue and are working on a fix. Before this issue occured in your save, do you recall losing any animals or items through the ground? Or did you travel to a larger island with cliffs etc? The team believe the issue may be related to the missing snakes issue reported by others so I am looking to keep track of any extra info around that for them.
